Proteins are three dimensional molecules made of strands of amino acids (imagine a ball of string).There are 20 different amino acids used in proteins found in living organisms.Some of these amino acids are polar and others are nonpolar.Where would a series of nonpolar amino acids most likely be located in a protein that is found in the cytosol of an animal cell?
A)On the surface of the protein
B)In the interior of the protein
C)At the very top of the protein
D)At the very bottom of the protein

Nonpolar amino acids are hydrophobic, so they would be most likely to be found in the interior of the protein away from the aqueous environment of the cytosol. This helps to stabilize the protein structure by minimizing interactions between the hydrophobic amino acids and water.
